Bell tones are only generated in the answer sequence by the answering
modem, so it shouldn't matter what the originating modem is set to.
It wouldn't surprise me that if they did actually recognise the fact that
limiting the setting to B0 stopped HST connects (which I doubt) that they
said:-  Oh no one will want a 16.8k connect anyway...

 BG> --------------------------------------------------------------------
 BG> An originating Dual Standard modem set to B1 sends out a Bell answer 
 BG> tone, which is the prevalent standard in the U.S. and Canada for 
 BG> connections at 2400 bps and lower.   At higher speeds, the Dual 
 BG> Standard also recognizes the ITU answer tones necessary for 
 BG> connecting with V. protocol modems, and adjusts to the answering
 BG> modem.   

Since when has an originating modem sent out an answer tone?  Also I didn't
know that there was a Bell standard for communication at 2400bps.

 BG> However, in Answer mode, a Dual Standard modem sending out the Bell 
 BG> answer tone (B1) won't be recognized by V. protocol modems.  The 
 BG> calling V. protocol modem, instead, will wait until it detects a 
 BG> tone it recognizes, the V.22 bis tone used at 2400 bps.   If you 
 BG> wish to have your Dual Standard connect with V. protocol modems at 
 BG> high speeds, make sure it is set to B0 for the ITU answer tones.  
 BG> It will also connect with HST modems at speeds up to 16.8K bps.

 BG> I've since asked Joe F in the USR echo, and expect an answer

Yes I saw this, so I didn't send a message myself..

... Sure when...  OINK FLAP.  OINK FLAP.  Well, I'll be damned...
